Connecting the Chassis Ground
The PROwatt 1000 has a screw terminal labeled CHASSIS GND on the
outside of the rear panel as shown in Figure3-4. Follow the guidelines in
“Grounding Locations” to connect the inverter’s chassis to the ground.
The neutral (common) conductor of the inverter AC output circuit is
connected to the chassis ground. Therefore, when the chassis is connected to
ground, the neutral conductor is also grounded. This conforms to National
Electrical Code requirements stating that separately derived AC sources
(such as inverters and generators) must have their neutral conductors tied to
the ground in the same way that the neutral conductor from the utility line is
tied to the ground at the AC breaker panel.

Grounding Locations

The chassis ground terminal must be connected to a grounding point. The
grounding point varies depending on where you install the PROwatt 1000.
Follow the guidelines that correspond to your type of installation:
Recreational Vehicle Connect the CHASSIS GND screw to the vehicle’s
chassis using 8 AWG copper wire (preferably with green/yellow insulation).
WARNING: Electrical Shock Hazard
Never operate the PROwatt 1000 without connecting it to the
ground. Electrical shock hazard could result.
